Chain Guard

This new unit from JNS will protect your cases from the damage caused by a thrown chain, and will also keep your pants, boots or foot safe from your countershaft sprocket.

The case saver portion is laser cut from 0.25" aluminum and then has the 0.19" aluminum countershaft sprocket cover welded to it and the entire unit is powder coated black.

All the mounting hardware is stainless steel with machined aluminum spacers also included.

If you have a 16t front sprocket, mounting modification may be needed to fit. Install the case saver on the bike without the top spacer and bolt. This provides a little extra wiggle room. Add the top spacer and bolt after the bottom bolts are loosely threaded.

B&B fired up the CNC equipment for another beauty, a Front Sprocket Case Saver. A great investment the 6mm aluminum base will protect your engine cases should your chain ever break or derail. On top of that is a 4mm piece to keep your pants and other things out of the chain as well. This replaces the stock cover over the countershaft sprocket.

If you have a 16t front sprocket, mounting modification may be needed to fit.

This nice piece replaces your plastic sprocket cover and protects your engine case from a chain derailment or failure. The 3/16" (5mm) thick steel plate is adjustable to accommodate 14, 15 and 16 tooth sprockets. Includes mounting hardware.

Replace your lost or broken stock plastic chain guard with a JNS aluminum one. Laser cut, CNC formed, TIG welded, and powder coated a beautiful satin black. This is a direct replacement for the stock unit.

  Please note that this unit is a bit wider than the stock one and will have to be trimmed if you are running a big fat SuperMoto wheel/tire.

Stock chain guard crack and crumble on you? Won't happen to this unit CNC machined from 2.5mm marine grade aluminum. Polished to a beautiful sheen that will give your DR that little twinkle as well as better protection.
